TIMING IS CRITICAL FOR 5G Accurate network synchronization is critical for 5G. While 4G required frequency synchronization, 5G now requires frequency and phase synchronization to support advanced features such as TDD (Time Division Duplexing), CoMP (Coordination Multipoint), CA (Carrier Aggregation) and beamforming. Therefore, operators are turning to network synchronization relying on IEEE 1588 PTP (Precision Time Protocol) and SyncE (Synchronous Ethernet) as the preferred solution to synchronize every network element, in frequency and in phase, from the core to the radios. Whether you are...

Time Error/Wander EXFO's Time Error/Wander application provides all the key test metrics to validate the accuracy of the network synchronization. And thanks to the built-in high precision GNSS receiver, the test is easy to setup and ready to measure in only a few minutes. The application performs multiple Time Error measurements such as Maximum Absolute Time Error (Max |TE|), dynamic Time Error (dTE), constant Timer Error (cTE), Maximum Time Interval Error (MTIE), Time Deviation (TDEV), etc. The Time Error/Wander application automatically evaluates if the signal under test meets different...

TA-SYNC AND TA-SYNC PREMIUM The TA-Sync and TA-Sync-Premium are optional timing modules that include a multi-constellation GNSS receiver. These can be added to the FTBx-88260 module, available on the FTB 5GPro test solution, to provide a time reference for one-way latency or Time Error and Wander measurements. The TA-Sync connects directly to an active GNSS antenna (SMA) and provides a 1 PPS input (SMB) and EXT CLK option (SMB) that can be configured as input or output. The TA-Sync-Premium module integrates a higher accuracy GNSS receiver and supports clock holdover to perform measurement...
